<h1>About VISUalization Playground</h1>
<p>
VISUalization playground is a tool for exploring and visualizing multiple endpoints. It can be used to send simultanious SPARQL-queries to multiple endpoints using ajax request. Need help with SPARQL queries? Read the <a href="http://www.w3.org/TR/sparql11-query/">specification</a>.

<li>Select endpoint(s)</li>
<li>Edit selected endpoints</li>
<li>Optionally select predefined query</li>

When you have queried the endpoint, the standard visualization is the table, in which you can order your data if you wish. Now you can:
<ol>
<li>Visualize your data as you wish</li>
<li>Edit your visualization and data</li>
<li>Resize the resulted visualization</li>
<li>Copy url & share</li>
</ol>
